Ukraine cut its gas imports by one quarter last year, Naftogaz reports. Imports fell from 14.1 billion cubic meters in 2017 to 10.6 bcm. Domestic production – overwhelmingly in the hands of state-owned Naftogaz – increased last year by only 2.5%, to 21 bcm. At the same time, Ukraine’s GDP grew last year by an estimated 3.4%. In this context, the most likely causes for the import drop were increased energy efficiency and shifts to other energy sources.
